| 中文摘要: |
| 通过依托“青海省大坂山成矿带中西段1∶5万水系沉积物测量”项目的实施和综合研究,获得了较丰富的化探资料。对15种元素进行了统计分析,阐述了各元素富集离散特征和地球化学空间展布规律。利用聚类分析和R型因子分析,讨论了各元素之间的组合关系；结合构造、地层及成矿带特征,以及地球化学异常分布和元素地球化学特征划分了找矿靶区。 |
| 英文摘要: |
| Through the supporting project 1 to 50 thousand stream sediment survey on the middle part and westward of the Dabanshan metallogenic belt northern Qilian Mountain, author synthesizes abundant geochemical data. The author explains the character of enrichment and scatter of elements and geochemical space distribution regulation by statistical analysis of 15 elements, and summarizes the mainly ore-forming elements in the area are Au, Cu, Pb, W and Mo etc. elements. The thesis gets the further understanding of the distribution of the main ore-forming elements combined the structure stratum and the character of metallogenic belt. Author improves the research degree of geology and geochemistry, and provides the geochemical basis for application and study of fundamental geology.The thesis delineates four metallogenic prediction areas and divides seven prospects by the distribution characters of anomalys and elements. Author explains the prospect for direction and mainly minerals. |
